CERN document server: Document management system for grey literature in a networked environment

Conclusion In this paper we briefly described the current status of research in the field of digital libraries interoperability, mainly with respect to federated data processing such as permitted within the Open Archive Initiative framework. We then presented the CERN Document Server Software suite that is a free software package main-tained by CERN providing an online digital library solution for mid- to large-sized document repositories. The set of CDSware modules was described and the differ-ences with other existing tools briefly mentioned. Finally we have mentioned a typical usage statistics illustrating the scope of grey literature and networked con-ditions of the CERN Document Server. We pointed out that the current trend in grey literature management goes toward institutional repositories build upon the distributed and federated model. Further research is going on within the CDS collaboration in this area, focused particularly on (i) semantic interoperability using ontologies in distributed and federated data processing and (ii) ranking technologies when searching grey literature in OAI compliant repositories.     

Kinematics of cycling in relation to anterior knee pain and patellar tendinitis

The coronal and sagittal plane leg movements of 24 experienced male cyclists were assessed using video analysis while cycling on a Kingcycle windload simulator. The cyclists were grouped into those with a history of injury and an asymptomatic group on the basis of self-reported injury status. The ages, cycling experience, competition distances and competition speeds of the two groups were compared using Student's t-test. No significant differences (P < 0.05) were found for any of these variables. The maximum and minimum shank adduction, shank adduction velocities, knee flexion and ankle dorsiflexion values were also compared using Student's t-test. Significant differences were found at the point of maximum adduction (1.9 degrees; P = 0.019) and minimum dorsiflexion (4.9 degrees; P = 0.014). These differences indicated more dorsiflexion and greater abduction on the part of the symptomatic cyclists, supporting previous research that found that cyclists with a history of injury differ from those without a history of injury in the coronal plane leg movement patterns they adopt. Also, the most extreme medial position of the knee relative to the ankle occurred during knee extension. This supports the potential injury mechanism proposed by Francis (1986), which had previously only been examined using coronal plane kinematics.     

Early and continued participation in a work-site health and fitness program

This study examines social-environmental, physical-behavioral, and psychological factors influencing early and continued participation in physical activity. Data for the study were collected during the first six months of operation of a work-site Health and Fitness Center. The following sources were used to collect data (N = 403): 1) printouts of frequency of employee visits to the Health and Fitness Center; 2) a questionnaire; and 3) fitness files. Data measuring early (month one) and continued (month six) participation were obtained from printouts of frequency of employee visits. A questionnaire measured estimation of physical ability, attraction to physical activity, youth participation, social support, and convenience of the Health and Fitness Center. Fitness files were used to obtain measures of cardiovascular fitness, percent body fat, and recent participation. Linear discriminant analysis was conducted to determine the practical usefulness of the social-environmental, physical-behavioral, and psychological factors for classifying employees into categories of exercise adherers and nonadherers. A measure of exercise adherence was based on company policy of six visits each month. Results for early participation (month one) indicated that convenience, sex, youth participation, attitudinal commitment, and age discriminated (p less than .05) among adherers and nonadherers with 63% accuracy. At the end of six months, attitudinal commitment, sex, convenience, and estimation of physical ability discriminated (p less than .05) among adherers and non-adherers with 60% accuracy. In addition, when early participation in the health and fitness program served as the measure of recent participation for the six month analysis, recent participation and attitudinal commitment discriminated (p less than .05) between the two adherence categories with 75% accuracy. Adherers and nonadherers were classified with 66% and 85% accuracy, respectively.
